1947S/0054K
C. Measurements and Approximations of Total Radioactivity
1. Gaseous Effluents
a ~ Fission and Activation Gases
b.
The gaseous radioactivity released from the plant vent ismeasured by a pair of off-line monitors each usingGeiger-Mueller detector readings from these monitors.These monitor readings are correlated to isotopicconcentration based on isotopic analysis of a grab sampleusing a germanium detector. A noble gas grab sample isobtained and analyzed at least weekly. The isotopicmixture is assumed to remain constant between grab sampleanalyses. Containment purges, gas decay tank releases andair ejector discharge are all routed through the plant ventfor release. The gaseous radioactivity released from thesteam generator blowdown tank vent is measured by analyzinggrab samples with a germanium detector. The isotopicconcentrations are assumed to remain constant between grabsamples.
Hhen the plant vent measurements as indicated by theprocess monitors are below the lower limit of detection,the results of the grab samples are used to quantifyreleases. In addition, the individual batch release datais used to quantify the radioactivity discharged from thegas decay tanks, and containment.
Other potential pathways for releasing gaseousradioactivity are periodically monitored by collecting grabsamples and analyzing these samples with a germaniumdetector system.
Iodine s
Radioiodines released from the plant vent are monitored bycontinuous sample collection on silver zeolite cartridges.The cartridges are changed at least weekly and analyzedwith a germanium detector., The radioiodine releases areaveraged over the period of cartridge sample collection.
Other potential pathways for releasing radioiodines areperiodically monitored by collecting samples using charcoalcartridges and analyzing these cartridges with a germaniumdetector.
1947S/0054K

d.
Particulates
Radioactive materials in particulate form released from theplant vent are monitored by continuous sample collection onparticulate filters. The filters are changed at leastweekly and analyzed with a germanium detector. Theparticulate radioactivity is averaged over the period ofparticulate filter sample collection. Each filter isanalyzed for alpha emitters using an internal proportionalcounter. All of the plant vent particulate filterscollected during a quarter are used for the compositeanalysis for strontium-89 and-90 which is counted on aninternal proportional counter after chemical separation.
Other potential pathways for releasing radioactiveparticulates are periodically monitored by collectingsamples using particulate filters and analyzing thesefilters with a germanium detector.
Tri tium
Tritium released from the plant vent is monitored bypassing a measured volume of plant vent sample through awater column and determining the tritium,increase in thewater. An aliquot of the water is counted in a liquidscintillation spectrometer. Tritium is determined at aminimum sample frequency of weekly. The tritiumconcentration is assumed to remain constant between samples.
2. Liquid Effluents
a. Batch Releases
Each tank of liquid radwaste is analyzed for principalgamma emitters using a germanium detector prior torelease. The pre-release analysis includes dissolved andentrained gases. Volume proportional monthly and quarterlycomposites are prepared from aliquots of each tankreleased. The monthly composite is analyzed for tritiumusing a liquid scintillation spectrometer and gross alpharadioactivity using an internal proportional counter. Thequarterly composite is analyzed for iron-55 using a liquidscintillation spectrometer and for strontium-89 and-90using an internal proportional detector following chemicalseparations.
1947S/0054K
b. Continuous releases
For the continuous liquid releases of steam generatorblowdown tank and turbine building sump oily waterseparator, daily grab samples are collected and volumeproportioned for weekly, monthly and quarterly composites.The oily water separator weekly composite is analyzed forgross gamma and principal gamma emitters using a germaniumdetector. The steam generator blowdown tank weeklycomposite is analyzed for principal gamma emitters andiodine-131. The steam generator blowdown tank monthlycomposite is analyzed for tritium using a liquidscintillation spectrometer and for gross alpha using aninternal proportional counter. The steam generatorblowdown tank quarterly composite is analyzed for iron-55using a liquid scintillation spectrometer and forstrontium-89 and-90 using an internal proportional counterfollowing chemical separations. The results for each ofthe composites are averaged over the period of thecomposite. In addition, one grab sample of the steamgenerator blowdown tank is analyzed monthly for dissolvedand entrained gases using a germanium detector. Theresults of this analysis are assumed to remain constantover the period of one month.

E. Abnormal Releases
F.
On October 22, 1987, an unplanned release from a Unit 1 Gas DecayTank occurred when valve CVCS-1-667 was inadvertently left open. Therelease occurred inside the Auxiliary Building and was monitored bythe plant vent monitors. During this event, 6.68E-1 curies ofXe-133, 1.20E-2 curies of Xe-131m, 5.10E-3 curies of Xe-133m, 1.71E-4curies of Xe-135, and 2.98E-2 curies of Kr-85 were released. Thetotal activity of the release was 7.15E-l curies and the release ratewas determined to be 1.04E-l'L of Technical Specification Limit.
On December 9, 1988, an unplanned release from Unit 1 Vent Headeroccurred when a relief valve (RV-54) malfunctioned. The releaseoccurred inside the Auxiliary Building and was monitored by the plantvent monitors. During this event, 1.01E-3 curies of Xe-133, 2.64E-7curies of Kr-85m, 1.57E-5 curies of Xe-131m, 1.22E-5 curies ofXe-133m, 5.84E-6 curies of Xe-135, and 2.53E-5 curies of Kr-85 werereleased. The total activity of the release was 1.07E-3 curi es andthe release rate was determined to be 1.33E-4'L of TechnicalSpecification Limit.
On January 5, 1988, an unplanned release from Unit 2 Air Ejector Ventwas identified as a result of a missing cap on the test port. Atthis time, the exact release period could not be determined.However, based on the most conservative estimation the release periodwas determined to be July 20 through December 31, 1987. Based on thenoble gases mixture on January 5, 1988, and the estimated releaseperiod, 7.53E-2 curies of Xe-133, 2.85E-3 curies of Kr-85m, 1.27E-2curies of Xe-131m, 6.92E-3 curies of Kr-88, 2.88E-2 curies of Xe-135,2.59E-2 curies of Xe-138, 5.69E-3 curies of Kr-87, 5.29E-2 curies ofXe-135m and 7.86E-4 curies of Ar-41 were released during this event.The total activity of the release was 2.12E-l curies and the releaserate was determined to be 6.61E-5'X of Technical Specification Limit.
Effluent Honi toring Instrumentation
During the report period, there were several RE-18 (Liquid RadwasteEffluent Monitor) alarms due to the crud accumulation in the pipingdead legs shared by the Liquid Radwaste Discharge System and theSpent Resin Transfer System. This crud is transported to the RE-18monitor during the beginning of a discharge causing a RCV-18 tripwhich terminates the release. The residue in the line is thenflushed back to the Liquid Radwaste System after a sample is obtainedand analyzed.
A plant technical review group determined the corrective action toprevent recurrence is to develop and implement a design change toseparate the shared piping between Liquid Radwaste Discharge Pipingand the Spent Resin Transfer System.
1947S/0054K
MAJOR CHANGES TO LIQUID, GASEOUS AND SOLID RADHASTE TREATMENT SYSTEMS
During the report period, one ma]or change to the Liquid Radwaste Systemwas approved. Design change DCP M-35781 removed the Unit 1 monitor tanksfrom the Boric Acid Recycle System and converted them intoLaundry/Distillate Tanks which were added to the Liquid Radwaste System.A major change to the Solid Radwaste System also occurred during thereport period. Dry Active Haste and expended cartridge filters wereprocessed by a mobile shredding system prior to packaging the waste usingin-plant compactors. This change was controlled by Revision 8 toProcedure AP C-257. A description of the design change evaluations isincluded as Attachment l.
III. CHANGES TO THE PROCESS CONTROL PROGRAM (PCP)
The radioactive waste packaging Process Control Program (PCP), aspromulgated in DCPP Administrative Procedures AP C-253 and AP C-253Sl,was revised twice during the report period. Revision 8 to AP C-253"Process Control Program" combined with Revision 1 to AP C-253Sl"Dewatering Control Program", was a change which did not affect any PCP
formulas. This change to the DCPP procedures involved a reorganizationof the referenced vendor procedures in AP C-253 and AP C-253Sl tosegregate solidification from dewatering. Since no vendor proceduralrevisions were associated with these DCPP procedural changes there was noeffect on waste solidification. This revision was reviewed and foundacceptable by the Plant Staff Review Committee (PSRC) on July 30, 1987.Revision 9 to AP C-253 incorporated a change to the vendor's acidsolidification PCP procedure. This change involved requiring the fullscale chemical addition to be based on the successful specimen sampleversus a fixed amount. This full scale formula change corrected anoversight in the text and was within the scope of the Topical Report.This revision was reviewed and found acceptable by the Plant Staff ReviewCommittee (PSRC) on November 12, 1987.
Therefore, the above changes to the PCP did not reduce the overallconformance of the solidified waste product to existing criteria forsolid wastes. A copy of the changed pages are included as Attachment 2.

CHANGES TO THE ENVIRONMENTAL RADIOLOGICAL MONITORING PROCEDURE (ERMP)
There were no changes to the DCPP Environmental Radiological MonitoringProcedure (ERMP) during the report period.
CHANGES TO THE OFFSITE DOSE CALCULATION PROCEDURE (ODCP)
During the report period, one on-the-spot-change to the DCPP Offsite DoseCalculation Procedure (ODCP) was approved. This change was to render anomenclature change for two liquid radwaste tanks and will not reduce theaccuracy or reliability of dose calculations or setpoint determination.This change was reviewed and found acceptable by the Plant Staff ReviewCommittee (PSRC) on September 17, 1987. A copy of the change page isincluded as Attachment 3.
1987 LAND USE CENSUS
There were no changes from the 1986 Land Use Census. The 1987 Land UseCensus results are included as Attachment 4.

IX. RADIATION DOSE DUE TO GASEOUS AND LIQUID EFFLUENTS
1947S/0054K -28-
A.
B.
RADIATION DOSES
Radiation doses due to radioactive liquid effluents
The radiation dose contributions due to releases of radioactive liquideffluents to the total body and each individual organ for the maximumexposed adult have been calculated in accordance with the methodology inthe Offsi te Dose Calculation Procedure. Dose contributions, listed inTable 7, show conformance with Technical Specification 3.11.1.2.
Radiation doses due to radioactive gaseous effluents
The radiation dose contributions due to radioactive gaseous effluents atthe site boundary for the land sectors have been calculated in accordancewith the calculational methodology in the Offsite Dose CalculationProcedure. Each unit's dose contribution has been calculatedseparately. The meteorology conditions concurrent with the time ofdischarge were used in these calculations. In addition to the siteboundary doses, the dose to all age groups at the nearest residencewithin the low population zone for each of the land sectors and a fivemile infant milk dose in each of the land sectors is included. Dosecontributions, listed in Table 8 which represents the maximum dose of agegroups, organs, and geographic locations for the third and fourthquarters, show conformance with Technical Specifications 3.11.2.2 and3.11.2.3.
D.
E.
Radiation doses due to direct radiation (Line-of-Sight Plus Sky-Shine)-Closest site boundary (800 m)
For the Third and Fourth Quarters of 1987, the radiation dose isevaluated to be 1.82 E-1 mrem due to the presence of radioactive wastecontainers outside of plant buildings.
Radiation Doses Due to Chemistry Laboratory Radioactive Gaseous Effluents— Closest Site Boundary (800m)
The radiation doses due to Chemistry Laboratory Radioactive GaseousEffluents for the report period is evaluated to be 1.70 E-6 mrem.
40 CFR 190 Considerations
The release of radioactivity in liquid and gaseous effluents during 1987resulted in doses that are small percentages of the technicalspecification limits as shown in Tables 9 and 10. This coupled with thefact that there are no other uranium fuel cycle sources within eightkilometers of the Diablo Canyon Nuclear Power Plant shows conformancewith 40 CFR 190.
1947S/0054K -29-
J
F. Radiation doses from radioactive liquid and gaseous effluents to membersof the public due to their activities inside the site boundary.
1. Liquid effluents
The radiation dose to members of the public within the site boundarydue to the release of radioactive liquid effluents is negligible.This is because the discharge piping for liquid radwaste is mostlyburied in concrete walls, is located in remote or inaccessible areasor is underground. In addition, the quantity of radioactivityreleased was very low during 1987.
2. Gaseous effluents
The radiation dose to members of the public within the site boundarydue to the release of radioactive gaseous effluents are listed inTable ll for the year of 1987.

A summary of the evaluation that led to the determination thatthe change could be made in accordance to 10 CFR 50.59.
The existing Unit 1 Monitor Tanks were designed to receiveradioactive liquids. The conversion to enable these tanks toreceive Laundry drains in addition to evaporator distillate hasnot created the possibility for an accident or malfunction of atype not previously evaluated in the FSAR. These tanks retainthe same ventilation to the offgas system and auxiliary buildingspill retention as before. The function of the tanks will be toreceive waste streams which are currently collected in similarunshielded tank rooms.

RESPONSE'947S/0054K
This design change increases laundry wet washing capacity withexisting equipment. The Unit 1 Monitor Tanks were originallyprovided to receive evaporator distillate from the Boric AcidRecovery System. Since distillate could not be recovered fromthese tanks due to dissolved oxygen, low conductivity distillateis sent directly to the Primary Hater Storage Tanks and thevolume of distillate released has been greatly decreased. Theexpansion of laundry drain collection capacity enables greaterflexibilityfor processing laundry during outages.
A detailed des cripti on of the equipment, components andprocesses involved and the interfaces with other plant systems.
The tank conversion required the installation of interconnectingpiping, valves and controls to permit diversion of laundrydrains into the Laundry/Distillate Tanks (LDTs). The dischargeof the LDTs was diverted from the Processed Haste Receivers tothe inlet header of the overboard filters.An evaluation of the change which shows the predicted releasesof radioactive materials in liquid and gaseous effluents and/orquantity of solid waste that differ from those previouslypredicted in the license application and the amendments thereto.
There will be no increase in liquid release due to this change.Any increase volume of Laundry drain liquid will be offset bythe volume of distillate recovered which could not be recoveredin the past. Failure or overflow of the tanks will result inliquid flow to the auxiliary building sump for collection andfurther treatment. No increase in the gaseous effluentspredicted will result due to this change since the contents ofexisting drain collection tanks are degassed and vented. Thischange will not effect the quantity of solid waste since onlystorage capacity is added.-50-

b.
A summary of the evaluation that led to the determination thatthe change could be made in accordance to 10 CFR 50.59.
The 10 CFR 50.59 evaluation considered that the shredding systemwould process ll Ci of waste. It was assumed that 25'L of thewaste activity would become airborne requiring filtration by theintegral shredding HEPA filter system. The offsite release dueto waste shredding was calculated to be 0.3'X of Tech. Spec.limits. Based upon this calculated predicted release andmonitoring of the effluent, it was determined that the changecould be made without affecting offsite releases.
Sufficient detailed information to totally support the reasonfor the change without benefit of additional or supplementalinformation.

ITEM: c.
RESPONSE'TEM:
d.
RESPONSE:
A mobile shredding system service was procured to process.DANand cartridge filters. This service was procured to ascertainthe volume reduction which could be achieved for each of thesewastes. A DAN density increase from 33 lb/ft3 to 38 lb/ft3 anda VR of 4 for filters was anticipated. Substantial disposalcost savings based on the reduced waste volume was the majorreason to procure shredding services.
A detailed description of the equipment, components andprocesses involved and the interfaces with other plant systems.
The self, contained shredding trailer consisted of a remote wastefeed section, two stage shredder, waste loadout station,integral shredder HEPA filter system, trailer ventilation. HEPA
system, a common stack with a sampler and a fire protectionsystem. Electric power was the only interface to the trailer.Bagged waste was delivered to the trailer and bagged shreddedwaste was removed from the trailer and packaged using in-plantcompactors.
An evaluation of the change which shows the predicted releasesof radioactive materials in liquid and gaseous effluents and/orquantity of solid waste that differ from those previouslypredicted in the license application and the amendments thereto.
The 10 CFR 50.59 evaluation predicted no liquid releases and0.3X of the Tech. Spec. limit as the change in the gaseousrelease. No quantity of solid waste reduction was predicted inthe 50.59 evaluation because the actual VR was unknown anddetermining the VR was the reason the service was procured.

"THINK SAFETY"
DIABLO CANYON LAND USE CENSUS
Engineering Research conducted a land use census in the vicinity ofDiablo Canyon Power Plant. This census vas for 1987. The land use censusis required by Nuclear Regulatory Commission, Regulatory Guide 4.8"Environmental Technical Specifications for Nuclear Power Plants" and by theDiablo Canyon Power Plant Technical Specification 3.12.2. These bothrequire that a census be conducted at least once per year during the grovingseason (between June 1 and October 1 for the Diablo Canyon environs). Thecensus is to identify the nearest residence, the nearest milk animal and thenearest garden greater than 50 square meters (500 sq. ft.) producing broadleaf vegetation in each of the 16 meteorological sectors vithin a distanceof five miles.
The methods for conducting the census vere: direct contact withindividual land owners or tenants and property visits. The land ovners vereidentified from County records. The land owners and Tenants vere contactedpersonally or by phone between June 30 and September 30, 1987.
Contact with the land ovners or tenants and the property visitsidentified no household gardens greater than 500 square feet. No milkanimals were identified on these properties. Much of the area surroundingMe plant site is used for cattle grazing and there is a farm in theeastsoutheast sector (along the site access road) producing legumes andcereal grass (grains).
Results
The attached table and map summarize the land use census results. No
milk animals vere identified within the first five miles in any sector. Theonly garden or farm greater than 500 square feet is in the eastsoutheastsector. The farm is on the coastal plateau; it starts at approximately twomiles from the plant and extends to 4.5 miles from the plant. The nearestresidence is 1.55 miles north northwest of the plant. A total of eightpermanent residences vere identified within five miles of the plant.
